Abstract
A windguard is adapted to be attached to the frame of a crop pickup in overlying relationship to the pickup tine rotor so as to control the incoming flow of crop materials. A transversely extending crop hold down portion of the windguard is pivotally supported between the front ends of a pair of fore-and-aft extending support arms that are pivotally attached at their rear ends to the frame of the pickup so that the windguard can articulate as it is moved up and down relative to the pickup by engagement with inflowing crop material.
Claims9
In combination with a pickup that is mounted on the frame of a crop baler, an improved windguard comprising:
- rigid support structure pivotally mounted on said pickup for up and down swinging movement relative to the pickup about a first, rearwardly disposed transverse axis relative to the direction of travel of the baler;
- a crop material hold down device carried by said support structure in overlying relationship to the pickup for movement with the support structure during said up and down swinging movement thereof,
- said hold down device being pivotally connected to said support structure for independent up and down pivoting movement relative to the support structure about a second transverse axis spaced forwardly from said first transverse axis,
- said hold down device having a front end and a rear end,
- said second transverse axis being disposed intermediate said front and rear ends of the hold down device so that the front end of the hold down device extends forwardly beyond said second transverse axis and the rear end of the hold down device extends rearwardly beyond said second transverse axis;
- and
- a hanger element suspending the front end of the hold down device from said frame of the baler for rotating the hold down device about said second transverse axis in a manner to yieldably press the rear end of the hold down device downwardly against crop flow entering the baler.
